NCT06753968

Brief Summary

The purpose of this study is to investigate the short-term and long-term outcomes between natural orifice specimen extraction surgery (NOSES) and totally laparoscopic right hemicolectomy (TLRH). The hypothesis is that NOSES could achieve good short-term and oncological outcomes for right colon cancer patients.

Study Arms (2)

Laparoscopic Right Hemicolectomy With Transrectal/transvaginal Specimen Extraction (NOSES)

EXPERIMENTAL

The NOSES group employs two distinct methods for specimen extraction, both of which have been thoroughly outlined in previous studies. The first method, transvaginal extraction, begins with the irrigation and disinfection of the vagina, followed by a transverse incision in the posterior fornix. The assistant then utilizes oval forceps to carefully extract the specimen bag through the incision, which is subsequently closed with continuous full-thickness sutures, using barbed sutures to ensure secure closure. The second method, transrectal extraction, similarly begins with irrigation of the rectum using a dilute iodine solution, followed by a longitudinal incision along the anterior wall of the upper rectum. The specimen, along with the protective sleeve, is then removed using oval forceps, and the incision is closed with a continuous full-layer running suture once the specimen has been completely extracted.

Procedure: Laparoscopic Right Hemicolectomy With Transrectal/transvaginal Specimen Extraction (NOSES)

Totally Laparoscopic Right Hemicolectomy (TLRH)

ACTIVE COMPARATOR

Totally Laparoscopic Right Hemicolectomy (TLRH), which involves performing intracorporeal anastomosis and specimen extraction through a small abdominal incision, enhances the benefits of minimally invasive surgery In the TLRH group, following the stapled side-to-side anastomosis, a small horizontal incision is made about 2 to 3 cm above the symphysis pubis, at the junction of the pubic hairline, to allow for specimen removal.

Totally laparoscopic right hemicolectomy (TLRH), which involves performing intracorporeal anastomosis and specimen extraction through a small abdominal incision, further enhances the benefits of minimally invasive surgery. In the TLRH group, following the stapled side-to-side anastomosis, a small horizontal incision is made about 2 to 3 cm above the symphysis pubis, at the junction of the pubic hairline, to allow for specimen removal.
